The modern model of atom is unable to show the speed of atoms which make it less sure about its improved version.
Explanation:
The atomic model has under-went a drastic change in the past few decades. The first model was developed by Demoncritus in 450 B.C. which was accurate about the existence of atom as matter particles but he was inaccurate about the divisibility of matters.
Many other scientists have developed various models of atom over time, they are- John Dalton(1800), J.J. Thompson(1897), Ernest Rutherford( 1899), Neils Bohr. Neils Borh talked about the nucleus in his model and about the electrons orbiting the nucleus. However, this modern model lacked the observation of the speed of electrons.
Answer:
the products have more energy than the reactants
Explanation:
endergonic reactions require energy to be driven, and therefore the change in gibbs free energy is a positive change, due to the energy gained.
Answer:
The amount of peroxidase will be changed by changing the amount of turnip extract used.
Explanation:
A) Adding more or less buffer to the test tube.
<em>B) Changing the amount of turnip extract used.</em>
C) Adding different amounts of water to the mixture.
D) Using different types of turnip extracts prepared for us.
Peroxidase is an enzyme that degrades hydrogen peroxide (H₂O₂), releasing oxygen at the end of the reaction. One of the vegetable sources to obtain peroxidase is turnip (Brassica Napus).
The experiment on which the question is asked has to do with the reaction in which H₂O₂ participates, as a substrate, and the turnip extract containing the enzyme peroxidase, with a change in color due to the release of oxygen.
It is clear that, if the amount of turnip extract in the reaction is changed, the amount of peroxidase added will change.
